Abstract: ABSTRACT       A self-orienting, directionally sensitive particle velocity transducer with an axially magnetized magnet which, displaced by gravity, floats off-center in a chamber filled with ferromagnetic fluid.  Wire coils affixed coaxially to the chamber ends asymmetrically intersect the magnet's flux lines.  Axial chamber rotation results in gravitationally induced sideways movement of the magnet to maintain its equilibrium position.  An impinging sound wave causes relative movement between the low inertia chamber-coil assembly and the high inertia magnet, thereby inducing a voltage in the coils - a relatively high voltage for vertical movement due to vertical assymetry, but a relatively low voltage for horizontal movement due to horizontal symmetry.  Axial sensitivity is low because the ferromagnetic fluid filling the narrow gap between the magnet and the chamber ends resists relative axial movement and any induced voltages in the coils cancel.  Substitution of an eccentrically weighted, axially polarized, composite magnet divided into oppositely polarized halves allows a smaller chamber and makes assymetry/symmetry independent of gravitationally induced displacement, thus allowing configuration for any direction of sensitivity.

Abstract: TWO-WIRE DUPLEX DATA TRANSMISSION SYSTEM            Abstract A system for transmitting data in a full duplex made over two lines transmits data in one direction in the form of a duobinary dipulse line code format and in the other direction in either a duobinary 100% duty cycle or a bipolar 100% duty cycle line code format.  Separation of the signals in each unit is by both filtering and canceling.  Detection of the duobinary dipulse signal in the data unit receiving it includes demodulation to the baud frequency for improved accuracy.

Abstract: ABSTRACT          A calender wherein a permanently installed main roll cooperates with at least one exchangeable roll to provide a nip for the passage of a web of paper or the like.  The end portions of the exchangeable roll are mounted in bearings which are insertable into and extractible from sockets provided in levers which are pivotably mounted in the frame of the calender.  The calender has a transporting unit which is provided with grippers for the bearings and with motors which reciprocate the grippers to extract the bearings from their sockets after the levers are pivoted to positions in which the exchangeable roll is spaced apart from the main roll.  The transporting unit thereupon transfers the exchangeable roll onto a mobile rack which can be transported to a station where the exchangeable roll is repaired.  The same rack or a discrete second rack can deliver a refurbished exchangeable roll to the transporting unit for introduction of the bearings on the refurbished roll into the sockets on the levers in the frame of the calender before the levers are pivoted to move the refurbished roll into engagement with a running web or with the main roll.  Locking devices are provided to releasably hold the bearings in their sockets, and additional locking devices are provided to releasably hold the bearings in sockets which are provided on the rack or racks.  The transporting unit can constitute a robot whose grippers then constitute effectors and whose operation is automated to start a roll exchanging operation as soon as one or more sensors in the calender ascertain that the quality of the exchangeable roll is unsatisfactory for further treatment of running webs.

Abstract: Abstract The  dust  collection units  in a  rotary railroad car dumper installation are mounted over the hopper pit along one or  both  sides  of the cylindrical,  rotatable dumper frame so that  dust  ladened  air  can be  sucked directly into the dust collection units without the need for duct work and the col-lected dust can be returned directly to the pit without the need  for easily  clogged screw conveyors and small chutes.  A fixed enclosure means encloses the top and sides of the dumper frame and  form with air  shields mounted on  the  cylindrical dumper  frame,  a  rotary valve which restricts flow such that ambient air is sucked into the hopper pit by the dust collection units at velocities which exceed the capture velocity of the dust clouds created by dumping of the contents of the car.

Abstract: ABSTRACT            The hitching aid disclosed is for use with agricultural tractors.  It is used to allow the tractor to be backed onto a trailer, whereupon the trailer becomes automatically hitched to the tractor.  The aid includes a converging channel which receives the head of the trailer's draw-pin.  The channel draws the pin-head into a throat, thus aligning the pin before the pin enters the pin-receiving jaws.  Thus, any abusive loads due to mismatch, etc., are taken by the bulbous head of the pin and the channel, rather than by the shank of the pin and the jaws.

Abstract: ABSTRACT      Self contained radio transmitting state estimator mod-ules are mounted on power conductors on both sides of power transformers in electrical substations and on power conduc-tors at various places along electrical transmission lines.          They are electrically isolated from ground and all other conductors.  These modules are capable of measuring current, voltage,  frequency and power factor (or the fourier compo-nents thereof) the temperature of the conductor,  and the temperature of the ambient air.  The modules transmit these parameters to local receivers.  The receivers are connected by an appropriate data transmission link, to a power control center which allows determination of the state of the power system.  Appropriate control signals are transmitted back to the electrical switchgear of the system to bring it to the appropriate optimum state.  Direct local control may also be effected,  for  example,  the  prevention  of  overloading  a transformer.  A "donut" state estimator module comprises a novel hot stick operated hinge clamp and a novel voltage sensor which measures the current between an isolated capa-citor plate and ground.   The  donut measures  the  fourier components of voltage and current over a number of cycles and transmits the components  to the local receiver.  The local receiver derives the desired electrical measurements such as voltage, current, power factor, power, and reactive power  and  transmits  them  to local  or  remote  control stations.   Up to 15 donut modules may transmit on a single channel  to a  single  local  receiver.   Each  transmits  at intervals which  are  an  integral  number.   The  intervals between transmissions of all donuts do not have a common factor and the average interval is the desired transmission rate.  Each donut uses the zero crossover of current of its conductor  to  establish  its  transmission  interval.  The system  is  self-calibrating using known  reference  signals within the donut module.

Abstract: Abstract of the Disclosure A membrane-like material forming component is obtained by dissolving mineral crude oil, bitumen or an amphipathic lipid in a solvent to form a solution thereof, the solvent being selected from the group consisting of halogenated hydrocarbons and p-xylene and being capable of forming in the presence of water and the oil, bitumen or amphipathic lipid and inter-facial membrane-like material. Water is then admixed so as to cause the membrane-like material to form and the solution, water and membrane-like material are allowed to separate by relative densities, thereby forming a bottom layer of the solution, a top layer of water and an intermediate layer between the bottom and top layers, the intermediate layer comprising the membrane-like material. The membrane-like material is extended into the top layer of water from which it is  isolated. The membrane-like material upon being brought into air dissociates and leaves a component derived from the oil, bitumen or amphipathic lipid and which is active to form or regenerate membrane-like material, when recombined with the solvent and water.

IPC: C07D207/46
Filed: 1996-03-08
Abstract: A process is disclosed for direct isolation of captopril from a substrate of the formula <CHEM> wherein R is lower alkyl or lower alkoxy. In this process, the substrate is first treated with an aqueous alkali metal hydroxide capable of forming a water-soluble salt of the substrate, wherein the alkali metal hydroxide has a concentration of 4 M or greater. The substrate is then neutralized, preferably with a mineral acid. By this process, captopril may be directly crystallized from an aqueous solution, avoiding the prior art use of organic solvents and zinc treatment to reduce levels of sulfide and disulfide impurities, respectively. In an alternative embodiment, neutralization is carried out by use of a hydrogen-supplying ion exchange resin.
